More toys.

Shortly after getting into the wonderful world of 3D printing, i realised that not all 3D Printers are created equal. After starting a print i went to get work done, and kept a window running with a webcam, when i noticed smoke coming out of the extruder. It turns out that (most) Chinese printers don't have basic security features like MINTEMP and Thermal Runaway enabled, meaning if a thermistor fails [Read More]

Running a Docker Swarm on a Raspberry Pi Cluster.

For a long time i've wanted to experiment with running a small cluster on my Raspberry Pi's, but I've always had lots of other things to do. Recently i started moving my hosted services from my NAS onto a single Raspberry Pi, and came across a few older Raspberry Pi's, and thought now is a good a time as any, so here goes. Hardware used I used the following components: [Read More]

Arduinos, Arduinos everywhere!

Introduction I've been quiet for the past months, mostly because of summer, but also because I've been busy getting (re)aquatinted with circuit design. I haven't played around with electronics in 20 years, but when I recently got my hands on an Arduino "starter kit" I just had to try it out. My go-to platform for solving home automation has been the Raspbery Pi, but RPi's have a [Read More]

New Toys

Controlling a 3D printer with a Raspberry Pi Preface I finally got around to getting a shiny new toy in the form of a 3D Printer. The specific model is a Wanhao Duplicator i3 Plus. While it may not be the best in terms of quality, it's a nice "little" printer that, after a lot of tinkering, produces some fair prints. I've had my fair share of problems [Read More]

Raspberry Pi Sense Hat

I recently acquired a Sense Hat, and despite not having much use for it, i decided to have some fun and learning a little along the way. The hardware The Sense-hat is a little Hat for Raspberry Pi's that contains a bunch of sensors, along with a small 8x8 RGB LED Matrix. It contains the following sensors: Gyroscope Accelerometer Magnetometer Temperature Barometric pressure Humidity Along with the hardware, there's an [Read More]
